Abstract

In this paper, a novel folded quarter-elliptical wideband monopole antenna for portable wireless applications has been presented. The proposed antenna has been fabricated and experimentally offers a wideband performance from 850MHz to 6GHz at 6dB return loss or VSWR 3:1. At this reference RL/VSWR level, the proposed antenna covers most of popular portable wireless frequency services including GSM, GPS, PCS, DCS, UMTS, WLAN and WiMAX. It offers nearly omni-directional radiation patterns, especially at the lower bands of operation. As it is of a relatively small projection area and volume, this antenna is a promising candidate for modern portable wireless devices.
